Hi, sorry if this is a FAQ/known problem, but I just joined the list.
I'm Trying to make a 8 disk raid5 array and I'm having problems. Every time I
mkraid it get part way through and crashes the machine. It must not be a hard
crash because softdog catches it and reboots the machine. I get no error
messages either scsi or raid. I'm using kernel 2.2.9, on a IBM-PCserver 704
(there are two adaptec 2940's built into the motherboard), and 10 2.0gb seagate
baracuda's. Two of the drives are partitioned for raid1 (sde[1-3] & sdj[1-3]).
The other drives are partitioned for one swap partition and one raid5 partition.
I've had a raid5 array work for 4 drives but not 8 or 6. I'm working on 5 right
now, but it takes awhile. Any ideas? Thanks in advance.
Here's my conf files.
